Hyundai Sonata Transmission Fluid
The correct transmission fluid for the Hyundai Sonata, how much it takes, how often to change it, and how to check the level.
Quick answer
The Hyundai Sonata typically uses Hyundai ATF SP-IV / SP-IV RR (automatic). Refill capacity on a drain-and-fill is ≈ 4–4.5 qt drain-and-fill, with a common change interval of ~60,000 mi severe; up to ~100,000 mi normal. Dipstick: No. Use SP-IV for the 6-speed and SP-IV RR for the 8-speed — they are not interchangeable.
